[texts]Wake Visualization of a Full-Scale Tiltrotor in Hover - Lau, Benton H.
The objectives of this program were to measure the tip-vortex trajectory of a full-scale, hovering tiltrotor and to compare the vortex trajectory of the baseline rotor with that of the subwing rotor (first figure). The subwing, which is mounted at the blade tip, can split the strong concentrated tip vortex into two weaker vortices, and weakening the vortex can reduce the blade-vortex interaction noise...

[texts]Automatic Molecular Design using Evolutionary Techniques - Globus, Al
Molecular nanotechnology is the precise, three-dimensional control of materials and devices at the atomic scale. An important part of nanotechnology is the design of molecules for specific purposes. This paper describes early results using genetic software techniques to automatically design molecules under the control of a fitness function. The fitness function must be capable of determining which of two arbitrary molecules is better for a specific task...

[texts]A structural and thermal packaging approach for power processing units for 30-cm ion thrusters - Maloy, J. E.
Solar Electric Propulsion (SEP) is currently being studied for possible use in a number of near earth and planetary missions. The thruster subsystem for these missions would consist of 30 centimeter ion thrusters with Power Processor Units (PPU) clustered in assemblies of from two to ten units. A preliminary design study of the electronic packaging of the PPU has been completed at Lewis Research Center of NASA...

[texts]Nozzle exit exhaust products from space shuttle boost vehicle (November 1973 design) - NON
Principal exhaust species emitted at various altitudes for two trajectories of the space shuttle vehicle are presented. The exhaust composition is given for the nozzle exit plane on the basis of equilibrium chemistry. Afterburning of excess H, H2, and CO in the plume is accounted for. Species considered include HCl and Al2O3, which have been recognized as environmentally significant, as well as others such as H2O (produced by both the solid rocket motor and the orbiter main engine) which, althou...

[texts]Longitudinal aerodynamic parameters of the Kestrel aircraft (XV-6A) extracted from flight data - Suit, W. T.
Flight-test data have been used to extract the longitudinal aerodynamic parameters of a vectored-thrust aircraft. The results show that deflecting the thrust past 15 has an effect on the pitching-moment derivatives and tends to reduce the static stability. The trend toward reduction in the longitudinal stability also been noted by the pilots conducting the flight tests.

[texts]Simultaneous dual-band radar development - Liskow, C. L
Efforts to design and construct an airborne imaging radar operating simultaneously at L band and X band with an all-inertial navigation system in order to form a dual-band radar system are described. The areas of development include duplex transmitters, receivers, and recorders, a control module, motion compensation for both bands, and adaptation of a commercial inertial navigation system. Installation of the system in the aircraft and flight tests are described...

Two 61-cm-diameter eight-ply quasi-isotropic IM7/PEEK cylindrical shells were fabricated by automated fiber placement the NASA Langley Research Center using only infrared radiant heat to preheat the substrate and incoming composite uni-tape. The shells were characterized by ultrasonic c-scans for overall consolidation quality, and by optical microscopy and acid digestion for void content. Compression tests were also performed...

[texts]National Aeronautics and Space Administration Marshall Space Flight Center Space Transportation Directorate Risk Management Implementation Program - Duarte, Luis Albert
The US civil aerospace program has been a great contributor to the creation and implementation of techniques and methods to identify, analyze, and confront risk. NASA has accomplished mission success in many instances, but also has had many failures. Anomalies have kept the Agency from achieving success on other occasions, as well. While NASA has mastered ways to prevent risks, and to quickly and effectively react and recover from anomalies or failures, it was not until few years ago that a comp...

[texts]Preliminary results on an H-alpha map of the Gum nebula obtained with the D-z-A satellite - Blamont, J. E.
Hydrogen emissions, including telluric H alpha, in the terrestrial atmosphere were studied. The H alpha experiment was designed to use a monochromatic photometer that would provide measurements of weak H alpha emission originating at altitudes of a few hundred or thousand km, free of contamination by other telluric emissions. The Gum nebula was recorded by the instrument as a much more intense feature than the geocoronal emission...
